• Alarms on each floor and in hallways and stairways.

• Alarms in each room such as bed rooms and living 

rooms. 

Additional alarms increase the security.

Installation of alarm:

1. Detach the alarm from the mounting base by twisting 

counter clockwise. Use the mounting base to mark the 

screw holes on the ceiling. Use the enclosed screws and 

plugs to install the mounting base. Once the mounting 

base is installed on ceiling or wall, attach the alarm by 

twisting clockwise.

2. After mounting, test the alarm by pushing the test 

button on the top and get a loud alarm tone. 

Please note: The label in the product must not be removed 

as  it  contains  important  information  regarding  the 

product.

The alarm may NOT be placed:

• In dusty rooms
• At the top of high pointed ceilings or in ceiling corners 

or within 50 cm of a wall.

• In rooms where the temperature goes out side +4

o

 to 

38

o

C or above 90% relative humidity not condensing. 

• In kitchen, garage and fireplaces where damp,

gases and smoke could occur. Place the alarm where 

it is reachable in order to test the battery and for main

tenance.

Fault finding: If the smoke alarm activates without 

visible cause, the possible cause could be:
• Dust particles in the smoke chamber which can be re

moved by vacuuming the mesh.

• High humidity condensing which can be resolved by 

drying the smoke alarm.

If the smoke alarm does not work when the test button is 

pushed, the probable cause is a faulty battery and the 

smoke alarm must be replaced. 

Other information: Do not paint the alarm.

end of life. This is electronic waste which should be
